Philips keeps managing to repeatedly fix, and then break the Hue app. It has been stable and effective for well over a year (after a super painful stretch), but they’ve managed to once again render PhilipsHue nearly useless. For the past several weeks, PhilipsHue has been much slower to load, and now when you want to turn a light off, you quite literally have to touch the on/off button and wait 5-6 seconds before the light responds, if it responds at all (for reference, lights used to turn on/off in about a second). Worse, while you wait to see whether PhilipsHue will actually communicate with the Hue hub, PhilipsHue completely freezes. You can’t swipe up/down or touch anything and have PhilipsHue respond, and after the lights do respond, you have to wait another 5-6 seconds before PhilipsHue functions again. So if you want to turn off 3 lights, for example, it will take you 30-45 seconds. For as much money as I have tied up in my Hue lights, I’d like for Philips to test their app updates better before they release the update, and when they cause a major bug like this, I’d really like them to fix it much more quickly. In summary, the Hue lights are outstanding. PhilipsHue is either brilliant, or unusable for months at a time. Right now, it’s broken again.
